[PATCH v2 wayland] tests: Test proxy versions

[Derek Foreman]

Add a test that confirms that proxy versions are always 0 for display
and correct otherwise.

Signed-off-by: Derek Foreman <derekf at osg.samsung.com>

Changes from v1:
Make the global once at a high version, bind it with different versions

create a wl_pointer from the wl_seat to test version inheritance

also test the generated wl_seat/pointer_get_version instead of just
 wl_proxy_get_version
